Frederick Cohan studies the origins of diversity in bacteria. He is intrigued by what is the same and different about species and speciation across all walks of life, and has investigated how the unique combination of enormous population size and rare but promiscuous genetic exchange in bacteria affect bacterial speciation and diversity. He is working to develop what he calls an “idiot’s guide” to bacterial systematics—a system to identify the most newly divergent products of speciation even when we know very little about the ecological and physiological differences between new species. He is a professor of biology at Wesleyan University.Please email for any articles you do not have access to:fcohan@wesleyan.edu
